E 80 SPRING COMPANY, OF CLEVELAND, OHIO, A CORPORATION BRACING MEANS FOR TUBULAR FILLER MEMBERS.

Application filed September 25, 1926. Serial No. 137,691.

This. invention relates to improvements in cap closed tubular necks of automobile f More particularly,

members, such as the filler uel tanks and the like. the present inventiontubular members of the type provided with opposed cam portions with which co-operate locking portions of the cap portions are usually finger member. These cam formed on the lower edges of depending flanges arranged within and lying in planes substantially parallel with the cylindrical body wall portion of the tubular member. At

ing ends of these cam portions,

the inner or cap seatsaid flanges are provided with depending pro]ections forming stops for the \locking fingers of the cap member so as movement of the said bers.

this type is to limit relative rotary cap'and tubular mem- One objection with tubular members of that the depending stop porflanges are often bent radially outward by large and heavy portions out of gasoline filling nozz tubular members for tanks with which said les inserted into the fillin with fuel the tubular members are associated. As result of bending said'stop the path of travel of thelocking fingers of the cap member, relative rotary movement of said cap and tubular members is not limited, with consequent objectionable results.

The object of the present invention is to and' improved bracing means provide simple for said stop portions vent displacement the which effectively prereof by a gasoline filling nozzle or like device.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

Referring to the drawing, which repre sents one suitable embodiment of the invention,

is a top plan view of Fig. 1 is a vertical tubular member embod with a cap member app ing my invention ied thereto; Fig.2

said tubular member;

Fig. 3 is a cross sectional View thereof on the line 3 -3, Fig. 4;

and Fig. 4 is a vertical sectional View on theline 4-4, Fig. 2. The tubular member illustrated in the drawing comprises a sheet metal cylindrical body wall 1 provided an inwardly extendin minating in adepen at its upper end with annular flange 2 tering flange 3. At two sectional view of a of these depending flanges are suitably inclined to provide gradual cam portions 5, with which cam ortions the locking fingers of the cap mem er co-operate, as isusual and as will more fully appear hereinafter.

Each of said cam portions is provided at its inner or capseating endwith a dwell or rest ortion 6, on which the locking fingers o the cap member are adapted to seat when the cap member is in. fully seated position upon the tubular member. Just beyond said dwell portions. the depending flanges 3 are each provided with a depending lug or projection 7 which forms a stop for the locking fingers of the cap member when said fingers are moved upwardly along the cam portions. As a result of such limitation of relative rotary movement between the cap and tubular members, the locking fingers of the cap member are brought to rest on patent 1 of James S. Reid, No. 1,593,847,

granted July 27', 1926, and to which patent reference may "Briefly, said cap memberincludesa suit able body COIHPI'iSIHg'B, dome-shaped top portion 10 and 'a depending marginal skirt por tion 11, within which portions issuitably urposes of illustration is here be had, if desired.

crimpedat the junction thereof a relatively flat, annular supporting member 12'. Said supporting member is provided at its'inner circularedge with an upwardly extending flange 13, to which is suitably crimped the substantially circular, flat bod portion 14 of a locking member. Saidloc ing member is provided with a pair of diametrically op fingers 15, only one posed resilient locking said fingers extendof which .is here shown, ing downwardly and circular body portion. gasket 16 is prefoutwardly' from the ments at which erably provided which is adapted to lie between the horizontal flange 2 of 'the tubular member and the supporting member 12 of the cap member..

The cap member is applied to the tubular member in the usual manner of bayonet joint connections, the two locking fingers of the cap member being passed down through the recesses or passageways 4 of the tubular member. The cap member is then turned in a clockwise direction, as viewed in Fig. l, which causes said locking fingers to ride up the cam portion 5, the rotary movement of the cap member being continued until said fingers strike the stop portions or a'butlng upon the cam dwell portions 6. To remove the cap member, it is only necessary to turn it in the reverse direction as will be readily understood.

As thus far described, the tubular member and its co-operating cap member are of the same construction as disclosed in the above mentioned Reid patent, and the improvementforming the subjett matter-of the present application will now be described.

When large and heavy nozzles are inserted into the tubular member to fill with fuel the tank 17 with which the tubular mem her is associated, the depending stop portions 7 of flanges 3 are frequently bent radially outward, out of the ath of movement of the locking fingers of t e cap member as they ride upwardly along the cam portions 5, so that said stop portions are ineffective to limit relative rotary movement of the cap and tubular members. In order to maintain said point said fingers are reststop portions in proper functioning position, said stop portions are provided with integral extensions. 18, which are adapted to be bent radially outward into engagement with the cylindrical body wall 1 of the tubular memher, as clearly indicated in Fig. 4. As such extensions engage and extend at right angles to thecylindrical bodywall ofthe tubular member, radial outward displacement of the stop portions 7 is effectively prevented, and by means which is of extremely simple form so that practically nothing is added thereby to the cost of manufacture of the tubular member.

What I claim is:

A tubular filler neck adapted to be closed by a cap member having a locking finger, comprising a tubular body portion and a depending flange arranged therein and extending substantially parallel therewith, said flange having an inclined lower edge over which travels the locking finger'of the cap member when applying said cap member to and removing it from the filler neck, said flange being provided at the rear end of its inclined edge with a depending projection forming a stop for the locking finger of the cap member as said finger travels up said inclined edge, said stop projection having its lower end portion bent at right angles outwardly into engagement with said tubular body portion, thereby bracing said stop projection and preventing its being bent outwardly when a filling nozzle is inserted into the tubular body portion of the filler neck.

In testimony whereof I hereby afiix my signature.
